Application filed December 29, 1904. Serial No. 238,868.

To all whom it may concern:

Be it known that I, AMzr A. FREY, a citizen of the United States,residing at Martins Creek, in the countyof Northampton and State ofPennsylvania, have invented a new and useful Improvement in Plows, ofwhich the following is a specification.

My invention relates to improvements in plows, and more particularly tomeans whereby the moldboard may be adjusted in an angular position tovary the width of the furrow.

The object of the invention is to provide a simple, durable, andcomparatively inexpensive adjusting means for plows which will be welladapted for the purpose intended.

With-the above and other objects in view the invention consists ofcertain novel features of construction, combination, and arrangement ofparts, as will be'hereinafter described and claimed.

In the accompanying drawings, Figure l is a top plan view of a plow withmy improvements applied thereto. Fig. 2 is a side elevation of the same.F ig. 3 is a detail rear end elevation of the plow-beam. Fig. 4 is adetail vertical longitudinal sectional view through the rear end of theplow-beam and the adjusting means, and Fig. 5 is a perspective view ofthe apertured bar or rack of the adjusting device.

Referring to the drawings by numeral, 1 denotes the plow-beam, and 2denotes a plow the standard 3 of which is pivotally mounted in ametallic sleeve 4, which extends through the beam 1. The plow 2 carriesthe usual handles 5 and is adapted to be adjusted or held in any desiredangular position by my improved adjusting and locking device 6. Thelatter comprises an apertured bar or rack 7, which connects the handles5 and which is slightly curved on an arc concentric with the pivot ofthe plow. This rack-bar 7 is channeled on its under side, as shown inFig. 4, and has its flanges provided with alining openings 8. Saidrack-bar has its opposite ends bolted or otherwise secured to thehandles 5 and is adapted to slide in a guide 9, which is secured uponthe under side of the rear end of the plow-beam. This guide ispreferably formed by bending a strip of metal, as clearly shown in Figs.2 and 4 of the drawings, so as to form a guide-loop 10 to receive therack 7 and a dependin apertured lug 1 1. A locking-b olt 13 is slidab lymounted in registering openings in the vertical portions of theguideloop 10 and in the lug 11. Said openings are adapted to registerwith the openings 8 in the rack-bar, so that the bolt 13 may passtherethrough to lock the said parts together. A coil-spring 14, whichsurrounds the reduced end 12 of the bolt be tween the loop 10 and lug11, is adapted to hold said bolt normally in its closed or proj ectedposition, and said bolt is adapted to be retracted to release the rack 7by a bell-crank 15, which is pivoted, as shown at 16, in a recess formedin the end of the beam 1 and has its lower bifurcated end pivotallyconnected to the projecting end 12 of the bolt, as shown at 17 Theopposite end of said bellcrank is pivotally connected by a link 18 to apivoted handpiece 19 on an operating-lever 20. The latter has its lowerend pivoted in a recessed bracket-plate 21, which is secured upon theupper side of the beam 1, as clearly shown in Fig. 4 of the drawings.

The construction, operation, and advantages of this invention will bereadily understood from the foregoing description, taken in connectionwith the accompanying drawings. It will be seen that as the handpiece 19and the end of the lever are grasped and the latter is moved forwardlythe bell-crank 15 will move the sliding bolt 13 rearwardly against thetension of the spring 12, so as to disengage the forward end of saidbolt from the rack 7. When the bolt is in this position, the plow may beadjusted at any desired angle with respect to the beam and may besecured in such adjusted position by permitting the bolt 13 to passthrough alining apertures 14 and 8, as will be readily understood.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of a beam, a plow pivotally mounted thereon, a framecarried by said plow, a. guide-loop upon said beam, an apertured barslidable in said guide and secured to said frame, a sliding bolt insaid. guide adapted to enter the apertures in said bar to lock said plowto said beam, and means for operating said sliding bolt.

2. The combination of a plow-beam, a plow pivotally mounted thereon, ahandleframe carried by said plow, a guide-loop se- IIO cured upon theunder side of said beam and and a lever for operating said bell-crank,sub

formed with an apertured lug and a loop hav stantially as described.
